Abstract
BackgroundUnstable pelvic ring injuries often involve high mortality and morbidity. This study was aimed to evaluate the modified minimally invasive pedicle screw–rod fixation for anterior pelvic ring injuries, in the respects of its feasibility, merits, and limitations.MethodsTwenty-three patients with unstable pelvic ring injuries underwent the modified anterior pedicle screw–rod fixation, with or without posterior fixation. The clinical outcomes were assessed using Majeed scores, and the quality of reduction was evaluated according to the criteria of Matta.ResultsMajeed scores showed that the clinical outcomes at postoperatively 1 year were excellent in 14 patients, good in 7, and fair in 2. One woman complained of persistent pain at the pubic tubercle during sexual intercourse. Iatrogenic neuropraxia of the unilateral lateral femoral cutaneous nerve occurred in 3 patients. Unilateral femoral nerve palsy occurred in 1 patient. The reduction was found to be excellent in 12 patients, good in 8, and fair in 3. Heterotopic ossification occurred in 8 patients, all being asymptomatic.ConclusionsThe modified pedicle screw–rod fixation with the minimally invasive technique offered an effective alternative for unstable anterior pelvic ring injuries.
Highlights
Unstable pelvic ring injuries often involve high mortality and morbidity
Minimally invasive techniques have been widely used for anterior pelvic ring fixation, whose potential benefits may include reduced blood loss, fewer soft tissue infections, better pain control, and faster

Summary
Unstable pelvic ring injuries often involve high mortality and morbidity. This study was aimed to evaluate the modified minimally invasive pedicle screw–rod fixation for anterior pelvic ring injuries, in the respects of its feasibility, merits, and limitations. Pelvic fractures represent a relatively small rare injury, but high-energy pelvic ring injuries often involve high mortality and morbidity [1]. Anterior pelvic external fixation is helpful for initial hemodynamic stabilization with less operating time and blood loss than open plating. Successful treatment of unstable pelvic ring injuries remains a challenge for orthopedic surgeons. Minimally invasive techniques have been widely used for anterior pelvic ring fixation, whose potential benefits may include reduced blood loss, fewer soft tissue infections, better pain control, and faster
